Django：ModuleNotFoundError：沒有名為“mysite.notes”的模塊

Question

我嘗試創建一個 django 項目。 我在 url 配置方面有一些問題。 找不到我需要的模塊。 這是我的目錄的層次結構： .

 ├── db.sqlite3
    ├── manage.py
    ├── mysite
    │   ├── asgi.py
    │   ├── __init__.py
    │   ├── __pycache__
    │   │   ├── __init__.cpython-37.pyc
    │   │   ├── settings.cpython-37.pyc
    │   │   ├── urls.cpython-37.pyc
    │   │   └── wsgi.cpython-37.pyc
    │   ├── settings.py
    │   ├── urls.py
    │   └── wsgi.py
    ├── notes
    │   ├── admin.py
    │   ├── apps.py
    │   ├── __init__.py
    │   ├── migrations
    │   │   ├── 0001_initial.py
    │   │   ├── __init__.py
    │   │   └── __pycache__
    │   │       ├── 0001_initial.cpython-37.pyc
    │   │       └── __init__.cpython-37.pyc
    │   ├── models.py
    │   ├── __pycache__
    │   │   ├── admin.cpython-37.pyc
    │   │   ├── __init__.cpython-37.pyc
    │   │   ├── models.cpython-37.pyc
    │   │   └── views.cpython-37.pyc
    │   ├── tests.py
    │   └── views.py
    └── static
        └── templates
            ├── __init__.py
            └── note.html

我已經編輯了 urls.py 文件：

from django.contrib import admin
from django.urls import path, include
from mysite.notes import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.home, name="home")
]

當我嘗試運行我的服務器時，它說：

Traceback (most recent call last):

Answer 1

如您所見，沒有模塊名稱 mysites.notes。 我想你是想從筆記應用程序導入文件。 您可以通過使用導入

from notes import app #here I am importing apps.py but you can import any file.

您遇到此錯誤的原因是 Django 服務器是從任何文件夾之外的 manage.py 文件運行的，因此所有路徑都從該文件映射。
